Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.
Bitcoins are a form of virtual currency. In other words, they are a type of money that does not exist in the actual world. However, they can be used to purchase actual products and services from real companies.
The bitcoin system was created in 2009 by an enigmatic person named Satoshi Nakamoto. In fact, no one is sure if Satoshi Nakamoto is an actual person or a group of people. Bitcoins are designed to serve as an alternative to national currencies, such as dollars and euros, They can be used to pay for things instead of cash or credit cards. When bitcoins are transferred from a buyer to a seller, the transaction is recorded in a public database.
Governments are concerned that bitcoins can easily be stolen by hackers. It has dawned on them that they might be used for illegal purposes. For example, stolen goods could be purchased without the government's knowledge. Although more and more companies are beginning to accept bitcoins, the percentage of purchases made using bitcoins is minuscule compared to other online payment methods, such as credit cards. Instead, many bitcoin owners simply keep them as an investment since more valuable in the future.
This may or may not be a wise approach. Currently, the value of bitcoins is fluctuating wildly, especially when compared to highly stable national currencies, Bitcoin Investors are gambling on the hope that as this high-tech money becomes more widely accepted, its value will soar.

Dịch bài đọc:
Bitcoin là một dạng tiền ảo. Nói cách khác, chúng là một loại tiền không tồn tại trong thế giới thực. Tuy nhiên, chúng có thể được sử dụng để mua các sản phẩm và dịch vụ thực tế từ các công ty thật.
Hệ thống bitcoin được tạo ra vào năm 2009 bởi một người bí ẩn tên Satoshi Nakamoto. Trên thực tế, không ai chắc chắn Satoshi Nakamoto là một người thật hay một nhóm người. Bitcoin được thiết kế để phục vụ thay thế cho các loại tiền tệ quốc gia, chẳng hạn như đô la và euro. Chúng có thể được sử dụng để thanh toán trực tuyến thay cho tiền mặt hoặc thẻ tín dụng. Khi bitcoin được chuyển từ người mua sang người bán, giao dịch được ghi lại trong cơ sở dữ liệu công khai.
Chính phủ lo ngại rằng bitcoin có thể dễ dàng bị đánh cắp bởi tin tặc. Họ nhận ra rằng chúng có thể được sử dụng cho mục đích bất hợp pháp. Ví dụ, hàng hóa bị đánh cắp có thể được mua mà chính phủ không biết. Mặc dù ngày càng có nhiều công ty bắt đầu chấp nhận bitcoin, nhưng tỷ lệ mua hàng được thực hiện bằng bitcoin là rất nhỏ so với các phương thức thanh toán trực tuyến khác, chẳng hạn như thẻ tín dụng. Thay vào đó, nhiều chủ sở hữu bitcoin chỉ đơn giản giữ chúng như một khoản đầu tư vì có giá trị hơn trong tương lai. Điều này có thể hoặc không thể là một cách tiếp cận khôn ngoan. Hiện tại, giá trị của bitcoin đang biến động mạnh mẽ, đặc biệt khi so sánh với các loại tiền tệ quốc gia có tính ổn định cao, các nhà đầu tư Bitcoin đang đánh bạc với hy vọng rằng khi loại tiền công nghệ cao này được chấp nhận rộng rãi hơn, giá trị của nó sẽ tăng cao.
